Question
The generator of text problem 4.4 is 85% efficient, and the total capacity of the reservoir available for electric generation is 10 9 m 3
The generator of text problem 4.4 is 85% efficient, and the total capacity of the reservoir available for electric generation is 109 m3. It is half full at the start of the day. Use the prices for March 5, 2017.
Problem 4.4 - In a conventional hydroelectric plant, the head is 70 m and the volume flow rate of water past the turbine blades is 3200 m3/s.
The plant can pump water back to the upper reservoir with efficiency of 80%. The plant pumps at its full rating when prices are less than $16/MWh The plant sells at its full rating when prices are greater than $20.40/MWh What is the net revenue?
